Simplifying x2 + 19xy + 84y2 = 0 Reorder the terms: 19xy + x2 + 84y2 = 0 Solving 19xy + x2 + 84y2 = 0 Solving for variable 'x'. Factor a trinomial. (x + 7y)(x + 12y) = 0Subproblem 1
Set the factor '(x + 7y)' equal to zero and attempt to solve: Simplifying x + 7y = 0 Solving x + 7y = 0 Move all terms containing x to the left, all other terms to the right. Add '-7y' to each side of the equation. x + 7y + -7y = 0 + -7y Combine like terms: 7y + -7y = 0 x + 0 = 0 + -7y x = 0 + -7y Remove the zero: x = -7y Simplifying x = -7ySubproblem 2
Set the factor '(x + 12y)' equal to zero and attempt to solve: Simplifying x + 12y = 0 Solving x + 12y = 0 Move all terms containing x to the left, all other terms to the right. Add '-12y' to each side of the equation. x + 12y + -12y = 0 + -12y Combine like terms: 12y + -12y = 0 x + 0 = 0 + -12y x = 0 + -12y Remove the zero: x = -12y Simplifying x = -12ySolution
x = {-7y, -12y}
